FOREWORD 

This Indian Standard was adopted by the Bureau of Indian Standards, after the draft finalized by the Pesticides 
Sectional Committee had been approved by the Food and Agriculture Division Council. 

Oxyfluorfen emulsifiable concentrate is used as an agricultural insecticide. It is a selective herbicide, used to 
control weeds of broad spectrum leaved. 

Oxyfluorfen emulsifiable concentrate is generally manufactured to contain 20 and 40 percent (mini) of oxyfluorfen. 

In the preparation of this standard due consideration has been given to the provisions of Insecticides Act, 1968 
and the Rules framed thereunder. However this standard is subject to restrictions imposed under the Act and 
Rules wherever applicable. 

For the purpose of deciding whether a particular requirement of this standard is complied with, the final value, 
observed or calculated, expressing the result of a test or analysis, shall be rounded off in accordance with 
IS 2 : 1960 'Rules for rounding off numerical values {revised)'. The number of significant places retained in 
the rounded off value should be the same as that of the specified value in this standard.

Specification 

3 REQUIREMENTS 

3.1 Constituents 

3.1.1 The material shall consist of oxyfluorfen, 
technical dissolved in suitable solvent(s) together with 
emulsifying agents and with or without stabilizers. 

3.1.2 Oxyflurofen, technical employed in the 
manufacture of the material shall conform to 
IS 14934. 

3.2 Physical 

3.2.1 Description 

The material shall be in the form of clear, 
homogeneous, stable liquid, free from visible 
extraneous impurities. On dilution with water, it shall 
readily form an emulsion. 

3.2.2 Cold Test 

No turbidity or separation of solid or oily matter shall 



occur when the material is subjected to the cold test at 
10°C as prescribed in 13.1 of IS 6940 or at any other 
lower temperature as agreed to between the purchaser 
and the supplier. Introduction of a seeding crystal is 
not necessary for the test. 

3.2.3 Flash Point (Abel) 

When determined by the method prescribed in IS 1448 
[P : 20], the flash point of the material shall be above 
24.5°C. 

3.2.4 Emulsion Stability 

Any separation including creaming at the top of 
sedimentation at the bottom of 100 ml of emulsion 
prepared in standard hard water with 2.0 ml of the 
EC, shall not exceed 2.0 ml when tested by the method 
prescribed in 13.3 of IS 6940. 

3.3 Chemical 

3.3.1 Oxyflourfen Content 

When determined by the method prescribed in 
Annex A of IS 14934 the observed Oxyflourfen 
content, percent (mini) of any of the samples shall not 
differ from the declared nominal value by more than 
the percent tolerance limits indicated below:

3.3.1.1 The actual value of Oxyflourfen content in the 
formulation shall be calculated to the second decimal 
place and then rounded off to the first decimal place 
before applying the tolerances given in 3.3.1. 

3.3.2 Acidity or Alkalinity 

When tested by the method prescribed in 13.5 of 
IS 6940 the acidity (as H 2 S0 4 ) or alkalinity (as NaOH) 
of the material shall be not more than 0.5 percent by 
mass. 

4 PACKING 

The material shall be packed in mild steel drum 
suitably lacquered with epoxy resin from inside. The 
general requirements as given in -IS 8190 (Part 2) shall 
also be followed.
